Decorator, furniture designer, wedding guru — you may have also seen her on TV. Her shimmering Beverly Hills bedroom would make anyone feel like a star.

Jane Margolies: When I see you on HGTV, you're so full of energy. Do you just bound out of bed in the morning?

Erinn Valencich: Actually I hit snooze, roll over, and sleep for another half-hour. My bed is so comfortable!

And beautiful. It's one of three beds in your furniture collection. What inspired the design?

Morocco was one influence. I wanted a sculptural headboard that would feel modern and elegant. The antiqued mirror and silver leaf give it the look of oyster shell. I'm sick of fully upholstered headboards.

It is padded, though. Is that for a softer look? For comfort sitting up in bed?

An upholstered headboard just adds a nice softness. The bedroom has a lot of hard surfaces — nightstands, armoires. There aren't a ton of soft goods.

What came first here, the bed or the wallpaper?

The wallpaper. I used it on a job a few years ago and loved it. There were a few rolls left but not enough for all four walls, and the colorway had been discontinued so I couldn't buy more. So I painted two walls and used the paper on the other two.

The colors are so tranquil — seafoamy blue-green, ivory, that soft metallic gold. Yet I know you're not color-shy.

I like a softer bedroom, even with dark colors. My last bedroom was deep purple, lavender, and gray. This room has lots of light, so I played off that.

That gorgeous wavy stripe on the pillow — that has slightly more intense versions of the wallpaper colors.

I'm obsessed with that fabric. I've tried to get clients to use it for years. It's from Old World Weavers and is extremely expensive, but I only needed a small amount.

There's a shimmery quality to it, and also to the wallpaper, the bed, the lamps...

The matte gold on those lamps is so pretty.

Isn't mixing silver and gold tricky?

Gold and silver are totally fine together. I wouldn't put a gold faucet in a bathroom that has a lot of silver door handles. But otherwise I don't think it matters. We wear black and navy today, and that used to be a no-no.

The duvet is from Calvin Klein. I've had it for years. The sheets are Macy's Hotel Collection, their highest-end line. They wash up really soft. It's so disappointing to get into a bed with sand papery sheets. I'm renting an apartment in Paris for three weeks, and I'm taking my sheets with me!
